Bard's code naming style guide
When naming variables in code, you can follow these best practices:
Descriptive: Choose names that are easy to remember.
Concise: Use clear and concise names.
A longer name needs to earn its length vs a shorter one by being more informative.
Lowercase: Use lowercase letters.
Underscores: Use underscores to separate words in a name.
No spaces: Avoid using spaces in names.
No special characters: Avoid using special characters.
No acronyms: Avoid using acronyms and abbreviations.
No conflicts: Avoid names that could be confused with keywords or built-in functions.
